SLIDING BEARING, BASE ISOLATION STRUCTURE, AND STOPPER FOR THE SLIDING BEARING
PROBLEM TO BE SOLVED: To cope even with unexpected great earthquake vibration while suppressing size increase and simplifying a structure.SOLUTION: A sliding bearing 20 includes a lower shoe 21 fixed on a lower structure, an upper shoe 22 fixed on an upper structure and arranged to be relatively displaced in a horizontal direction with respect to the lower shoe 21, and a slider 23 positioned between the lower shoe 21 and the upper shoe 22 and disposed on a sliding surface 24 provided on at least one of the lower shoe 21 and the upper shoe 22 to be slid in the horizontal direction. The slider 23 is slid on the sliding surface 24 to the horizontal direction in accordance with relative displacement of the lower shoe 21 and the upper shoe 22 to the horizontal direction, and to one of the lower shoe 21 and the upper shoe 22, a stopper 31 which regulates further relative displacement of the lower shoe 21 and the upper shoe 22 by being abutted to the other from the outer side of the horizontal direction when the lower shoe 21 and the upper shoe 22 are relatively displaced in the horizontal direction is connected.
【課題】大型化を抑制して構造の簡素化を図りつつ、想定外の大きな震動が生じたときにも対応する。【解決手段】すべり支承２０は、下部構造に固定される下沓２１と、上部構造に固定され、下沓２１に対して水平方向に相対変位可能に配置される上沓２２と、下沓２１と上沓２２との間に位置し、下沓２１および上沓２２のうちの少なくとも一方に設けられたすべり面２４に、水平方向に滑動可能に配置されたスライダ２３と、を備え、スライダ２３は、下沓２１と上沓２２との水平方向への相対変位に伴って、すべり面２４上を水平方向に滑動し、下沓２１および上沓２２のうちのいずれか一方には、これらの下沓２１および上沓２２が水平方向に相対変位したときに、いずれか他方に水平方向の外側から当接することで、下沓２１と上沓２２との更なる相対変位を規制するストッパ３１が連結されている。【選択図】図５
